Help OC AM2 4600

Hi

i just bought an am2 4600 after the price drops with a m2n32-sli and with 2g of ocz pc2-6400 platinum kit...

so far, the lowest cpu setting that i've used is 2.6 at 1.45V and what i've got is unstability at 2.6 at 1.46V....im gonna try 1.5v tomorrow...

I dont know, it has been like a nightmare, 2.6 at 1.45V, unstable ...2.7 at 1.5V, unstable.......2.8 at 1.55V, unstable...

The only thing that i changed in bios is cpu fsb, cpu volt, and the ht links down from 5x to 4x...andmemory dividers to check if it was a memory problem and no...

I don't know if i just got a really bad chip or is this a mobo problem...any suggestions?

We'll need some more information re all system settings (like vdimm, memory timings & fsb) before any useful help can be given ... off the top of my head it sounds like the cpu isn't your problem.



 
ok...

at these settings pc is unstable

CPU FSB:217
MULT:12X
CPU VOLT:1.46V stock 1.4V
HTT LINK: 4X
MEM: DDR2-800 DIVIDER...system still unstable at DDR2-667 divider...(thats why i say its not a mem problem)
MEM VOLT:2.1V (default)
MEM CL: 4-5-4-15 (default) 2T

thats all what i've changed in the bios...

yes and it is even more since the boards overvolts by .03v...i know that it is the boards that does that and not mine since other people are having the same overvolting stuff
 
That's very odd, I have almost the same settings with my Asus M2N32 SLI, X2 4600+, 2GB Corsair 6400C4. I have also OC'd to 217 FSB and system is very stable for a week now:

FSB: 217
Multiplier: 12X
CPU voltage: 1.392V
HTT: 5X
RAM speed: 866MHz (800 divider)
RAM voltage:2.0V (default)
RAM latency: 5-4-4-12-2T (EPP High Performance setting)

At your RAM timings, can the OCZ RAM OC to the 866MHz? Although it has probably been reported that the OCZ can manage this, I've heard about people having problems with this RAM. Maybe you want to try more conservative timing.
 
find our how far each companent can go by themselves first.

use the the most relaxed memory timings you can use, and put the HTT x3.

take the ram completed out of the question, even use the lowest memory divider you can.
 
Try setting the RAM timing to 5-5-5-15 or something around there, and up the voltage on the RAM some more to 2.2V. If that does not work use the 533 MHz RAM divider. Also run memtest to make sure the RAM isn't the problem.

With the RAM out of the question, though, I'd try overclocking with a 11X multiplier (turn off C&Q first). and give the CPU 1.55-1.6V to find the max.

did you change the chipset voltage?

I didn't change it. As myocardia said, you don't have to. Most (probably almost all) X2s can go up 200MHz on stock voltage.
 
On my Foxconn Nforce 590SLI board the RAM seemed to sometimes like and try running 1T. So I had to specifically force it to 2T (while leaving other settings on auto). That's running 2x1GB G.Skill pc6400. And I'm running HTT 4x at 300mhz without any problem.

Is cooling an issue?
 
cooling is not an issue since i have a zalman cnps 9500am2 and 3 120mm fans in the case....

also the psu is not an issue since i have a brand new ocz gamexstream 600w
 
also, today when i ran prime at stock settings, one core failed after 6 hours while the other kept priming...it is weird because it is the same core that fails everytime first...i've ran like 5 times and everytime it is core 1 that fails before core 0.
